2025 Suzuki Ertiga

K15B

1.5L I4

A naturally aspirated, rev-happy four that trades turbo punch for honesty and durability, peaking around 105 PS high in the range. In the featherweight Jimny it feels willing rather than fast, which suits the car's go-anywhere brief.

Part of Suzuki's K-engine family, the K15B debuted in 2018 in the Maruti Ertiga and Ciaz before powering the fourth-generation Jimny. It is an all-aluminium, open-deck DOHC design developed largely for Suzuki's India-built global models.

• Suzuki deliberately gave the Jimny the older naturally aspirated K15B rather than a turbo, prizing simplicity and reliability for off-road duty.
• It uses lightweight low-tension piston rings and 'nut-less' split connecting rods to cut internal friction and weight.
• In several markets it pairs with Suzuki's mild-hybrid setup, replacing the alternator with an integrated starter-generator for regen and torque assist.
